Re: [O] [bug, babel] export corruption bug and 3 more bugs

[Eric Schulte]

Hi David,

Sorry it took me a while to notice this thread -- incidentally after a
patch to this effect was shared by Lawrence Mitchell in a separate
thread.  I've just applied Lawrence's patch, which should resolve this
issue as well.

Please let me know if the problem remains.  Now that this thread is on
my radar I should be more attentive to it.

Thanks -- Eric
